This paper presents a mathematical procedure for modeling rectangular (N rows with M modules each) and non-rectangular photovoltaic (PV) arrays in Total Cross-Tied (TCT) configuration operating in uniform and mismatching conditions. The proposed model uses the simple single diode representation for each PV module; then each row of the TCT array is represented as an equivalent non-linear PV circuit...
In this paper a novel approach to the Maximum Power Point Tracking (MPPT) in distributed PhotoVoltaic (PV) applications is proposed. It is useful when the granular control of the PV field is applied by adopting a dc/dc converter for each PV module. It consists of a single digital controller implementing a multivariable MPPT algorithm based on the Perturb and Observe (P&O) approach, acting on the...
